Add scaled column for Allocated Memory

[adamsitnik]

Suggested by @stephentoub

There's also no equivalent for the memory columns that I could find, which makes things inconsistent in the results, since some of these benchmarks are more about memory than they are about throughput.

Side note: The column should be visible when one of the benchmarks is marked as baseline

I'm on it.

@gsomix could you wait until I merge #878 ? I should merge it in 24h. It contains some things that would break your PR for sure (it's touching the columns for diagnosers)

[gsomix]

@adamsitnik OK, I'm just reading code for now. :)

[adamsitnik]

@gsomix I have merged the #878

@adamsitnik I'm looking for some guidance for this issue. There are classes for baselines (e.g. BaselineCustomColumn) that tightly coupled with Statistics. We don't have any statistics for memory usage, only raw numbers of allocated bytes or gc operations. Should I somehow reuse and refactor exist baseline columns, or just to create new one (like MetricScaledColumn)?

[adamsitnik]

@gsomix I think that you could detect if any of the Benchmarks have a basline, if so MemoryDiagnoser could return one more metric - scaled allocated bytes

I’ll take this if that’s ok!
